Arbitrary waveform ranging
The arbitrary waveform is described in normalized units from -1 to +1. See the fol-
lowing example:
Ranging: BEST
Amplitude: 10mA peak
Offset: 0mA
ARB values: range from +1 to -1
These settings will generate a waveform with a peak-to-peak value of 20mA on
the 20mA range.
Frequency
The frequency setting range for sine, square, ramp, and arbitrary waveforms is
from 1mHz to 100kHz. Note that the period is the reciprocal of the frequency: 1/f.
For example, a 1kHz waveform has a period of 1ms.
Offset
The offset setting allows you to add a DC offset value to a waveform. Figure 7-1
shows an example of a 1mA offset added to a square wave with a 10mA peak
(20mA peak-to-peak) amplitude.
